Facile synthesis and anti-proliferative activity evaluation of quinoxaline derivatives

A series of ?drug-like? compounds based on quinoxaline scaffold with arylsulfonyl hydrazinyl, arylformyl hydrazinyl or arylsulfonyl groups at C-2 and aryloxy groups at C-3, were synthesized in 4 or 5 steps involving cyclization, chlorination and coupling reactions. Cellular anti-proliferative activities of these quinoxaline derivatives in vitro were determined, which revealed that the inhibitory potency and selectivity of 6f was comparable to that of the positive control.

Observation of the set of the rhree sublevel phosphorescence spectra. III. External heavy atom effect on the phosphorescence spectra of quinoxaline and 2,3-dichloroquinoxaline

The sublevel phosphorescence spectra of quinoxaline and 2,3-dichloroquinoxaline are obtained in a light atom host such as naphthalene-d8 and 1,2,4,5,-tetramethylbenzene and in a heavy atom host such as 1,2,4,5,-tetrabromobenzene.Only the radiative decays, but not the nonradiative decays, are susceptibile to external heavy atom effect.For the phosphorescence from the in-plane sublevels significant heavy atom effect is observed for the 0-0 and some vibronic bands involving nontotally symmetric vibrations.For the phosphorescence from the out-of-plane sublevel, external heavy atom effect exists but the enhancement is very slight.These features are interpreted satisfactorily in the framework of a theory.The external heavy atom effect observed in 1,4-dibromobenzene differs sonsiderably, and the origin of the discrepancy is discussed.

Formation of 1-phenyl-4-oxo [1,2,4]triazolo[4,3-a]quinoxaline from 2- chloro-3-(2′-benzylidenehydrazino)quinoxaline during dehydrogenative cyclisation using cupric acetate

Attempted dehydrogenative cyclisation of 2-chloro-3-(2′- benzylidinchydrazino)quinoxaline 5 with a view to prepare 1-phenyl-4-chloro- [1,2,4]-triazolo [4, 3-a]quinoxaline 6 using cupric acetate gives 1-phenyl-4- oxo-[1,2,4]triazolo[4,3-a]quinoxaline 7. A rational explanation is offered for this reaction and the applicability of cupric acetate as dehydrogenative cyclisation agent (such as in the conversion of 10?11) has been demonstrated.

Synthesis of Novel Substituted Phenyl-3-Hydrazinyl-Quinoxaline-2-Amine Derivatives: Evaluation of Antimicrobial Activity and Its Molecular Docking Studies

New series of quinoxaline derivatives (4a?4h) were synthesized by treating 2-chloro-3-hydrazinyl quinoxalin (3) with various anilines. Compound 3 was obtained from the 2,3-dichloroquinoxaline 2 which was prepared from 4-dihydroquinoxaline-2,3-dione (1). All synthesized compounds (4a?4h) were characterized by various spectral techniques, that is, IR, 1H-NMR, mass spectroscopy, and elemental analysis and completion of reaction were confirmed by TLC. In vitro antimicrobial activity of synthesized compounds was evaluated using disc diffusion assay against gram-positive and gram-negative microbial strains, and then, the minimum inhibitory concentration and IC50 values of compounds were also determined. The results of antimicrobial study revealed that compounds 4e, 4g, and 4a were active and exhibited better inhibitory activities as compared with standard drug amoxicillin. Docking studies were performed by using Argus lab, and all the compounds exhibited good docking scores between ?9.53 and ?7.94?kcal/mol against dihydrofolate reductase protein fragment from Staphylococcus aureus (PDB ID-4XE6). Among all compounds, 4e has shown the maximum docking score and found in agreement to in vitro studies.

Syntheses and evaluation of 3-(3-bromo phenyl)-5-phenyl-1-(thiazolo [4,5-b] quinoxaline-2-yl)-2-pyrazoline derivatives

A variety of 3-(3-bromo phenyl)-5-phenyl-1-(thiazolo [4,5-b] quinoxaline-2-yl)-2-pyrazoline were obtained by the refluxing of 1-N-thiocarbamoyl 3,5-diphenyl-2-pyrazoline with 2,3-dichloroquinoxaline. The chemical structures of the compounds were elucidated by UV, IR, 1H NMR, and 13C NMR spectroscopy. The purity of the compounds was confirmed by their elemental analysis. The antiamoebic activity of these compounds was evaluated by microdilution method against HMI:IMSS strain of Entamoeba histolytica and the IC50 values were compared with the standard drug metronidazole. Some of the quinoxaline derivatives showed less IC50 values than metronidazole. To elucidate the toxic effect, MTT assay was performed using kidney epithelial cell line. The results showed that all the compounds are non-toxic.

Functionalization of gold nanoparticles with two aminoalcohol-based quinoxaline derivatives for targeting phosphoinositide 3-kinases (PI3Kalpha)

Quinoxaline derivatives have attracted considerable attention due to their vast range of applications that includes electroluminescence and biomedicine. Concerning the latter, the literature has shown that compounds with a quinoxaline motif bind quite efficiently to phosphatidylinositol-4,5-bisphosphate 3-kinases (PI3Ks), which are enzymes found to be overexpressed in some types of neoplasms. In the present study, gold nanoparticles (AuNPs) were easily functionalized with 2,3-diethanolminoquinoxaline (DEQX) and 2-(2,3-dihydro-[1,4]oxazino[2,3-b]quinoxalin-4-yl)ethanol (OAQX). We made use of glycerol in alkaline media as reducing agent and the quinoxalines served as capping ligands to stabilize the AuNPs. This is the first report on the modification of a nanostructure with quinoxalines. Functionalization confers nanoparticles the required specificity to target only cancer cells, which opens possibilities for phototherapy since the modified AuNPs would concentrate in the tumor tissue as a consequence of PI3Kalpha overexpression. Molecular dynamics simulations have shown that DEQX and OAQX are potential inhibitors of PI3Kalpha since they bind to the active site of the enzyme in a way similar to other known inhibitors.
